I don't see the problem really. If people want to waste time "hotlapping" again and again, so what? Sure, it's not within the spirit of the championship, but there will always be people looking for some advantage over others, you can't prevent that. There are a good number of amazing alien drivers around here, so I bet few or none of the hotlappers are scoring points anyway.
You also can't prove who is hotlapping and who isn't, and the last thing we need is people accusing each other. Just forget about what other people may or may not be doing, concentrate on your own performance, and have fun. That's what it's all about, at the end of the day.
